FISH of T31 hybrids. Shown are metaphase spreads of hybrids T31–3L7 (A), T31–2G3 (B), and T31–1O10 (C), respectively, hybridized with total genomic mouse DNA. The mouse DNA was prehybridized with mouse Cot-1 DNA to prevent hybridization of the many repetitive sequences in common between mouse and hamster.
